Yes, there has always been a plan to internationalize DiveLogDT/DiveLogManager and then localize it into other languages, German likely being the first. Unfortunately, the path to this has not gone well. We rely on volunteers for doing our translations as the person doing the translations really needs to be a scuba diver to know the correct terms to use in context. We had someone who volunteered to help us with DiveLogDT, but the commitment became too much and over too long a period. We also ran into some Apple limitations where their tools for doing this did not work with "old" legacy applications like DiveLogDT, unless large parts of it were re-written.

Going forward, I think the right answer is to not try and do it all at once, but to do it a small piece at a time. That would mean that for German users, the App would be in both languages at the same time, with some parts in German and some parts in English.

I will renew our efforts at getting this going again. When we're ready, I'll look for volunteers here to help with translating.
